CARBU R ETER.

SPECIFICATION formingpart of Letters Patent No. 664,467, dated December25, 1900.

Application filed May 24, 1900.

To aZZ whom it may concern.-

Be it known that I, JAMES FREDERICK BEN- NETT, engineer, a subject ofthe Queen of Great Britain, residing at No. 18 Violet Bank, Sheftield,inthe countyof York, England,have invented certain new and usefulImprovements in Carburetors, of which the following is a specification.

This invention relates to apparatus to be used in conjunction with a gasor oil engine of ordinary type in such a manner as to en able it to beworked with ordinary oils of high flashing-point.

The generator consists of a closed vessel provided with means forheating it. The heating means may consist of a coil of pipe arranged inthe generator and adapted to cir- Inside the vessel there are one ormore jets so arranged that air is forced or drawn through the liquidhydrocarbon and becomes carbureted. These jets are formed by admittingair between two parallel disks,whose distance apart is adjustable, sothat the air-supply can be regulated. The jet or jets are preferablyused in connection with a perforated plate, whereby air is caused tospread and become divided into minute streams or bubbles, thus causingthe air to be readily carburet-ed. A convenient arrangement is to placeone or more perforated plates above the jet in the vessel. Oil may besupplied to the air-feed pipe or to the generator in any suitable way.

In the accompanying drawings, Figure 1 shows a vertical section of thegenerator. Fig. 2 is a detail view, on an enlarged scale and in section,showing the manner of connecting the telescopic pipes at their upperends. Fig. 3 is a detail view in perspective of the disks at the lowerends of the tubes.

The generator at consists of a closed vessel heated by coil b, which maybe connected to the exhaust-pipe c of an engine. Air is drawn into thevessel a by air-pipes d and e through holes 6 at the bottom of thelatter pipe and between the disks d e, fixed to the pipes. The pipe eslides telescopicallyin the pipe d, being pressed downward by the springf and its position regulated by the nut c working on a screw on the stem6 fixed to it. a at are perforated diaphragms fixed in the vessel SerialNo. 17,839. (No model.)

a above the disks d e. The vapor or gas produced in the vessel (1 passesout by the pipe g. The arrangement is such that air may be forced ordrawn through the liquid hydrocarbon in the vessel CL and becomethoroughly carbureted. The air passes down through the pipes d and e andout through the holes 6 between the disks d e and then ascends throughthe hydrocarbon. In ascending it passes through the perforated plates 0.a and thereby becomes divided into minute streams or bubbles beforerising to the surface of the hydrocarbon.

I have shown two perforated plates. Only one need be employed, or theplates may be difierently arranged, as long as the construction is suchthat air after passing out through the holes 6 is made to pass throughperforations before reaching the surface of the hydrocarbon.

The distance between the disks may be varied by the adjustments abovereferred to, and thus the size of the openings e may be varied; but itis immaterial whether or not the distance apart of the disks affects thesize of the holes e as the increased friction be-.

tween the air and the disks when the latter approach each other is quitesuflicient to regulate the supply.

I claim as my invention- 1. In a generator for hydrocarbon-motors, thecombination of a vessel for containing liquid hydrocarbon, two paralleldisks in the lower part of the vessel, means for supplying air betweenthe disks, means for varying the distances of thedisks apart, and anoutlet for the carbureted air from the vessel.

2. In a generator for hydrocarbon-motors, the combination of a vesselfor containing liq uid hydrocarbon, an air-supply pipe terminating inthe lower part of the vessel, two parallel disks at the bottom of thepipe, means for varying the distances of the disks apart, and an outletfor the carbureted air from the vessel.
